IMPROVEMENT IN WEIGHING MECHANISMS FOR CARDlNG-MACHINES.

Specification forming part of Letters Patent No. 196,424, dated October 23, 1877; application filed May 25, 1877.

To all whom it may concern:

Be it known that I, M. G. BRAMWELL, of Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in NVeighing Mechanisms for Oarding-Machines andI do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,whioh form part of this specification. v

My invention relates to scales and feeders for carding-machines, and is intended as an improvement upgn Letters Patent No. 180,533, dated August 1, 1876; and the nature of my invention consists in the construction and arrangement of devices, as will be hereinafter more fully set forth, and pointed out in the claims.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation, Fig. 2 avertical section, and Fig. 3 a detail view, of my invention.

The scale consists of two arms, A A, which work on knife-edges or pivots a a, in stationary hooks B B, and said arms are attached, at such distances apart as to suit the width of the carding-machine, by rods 1) I). These arms have notches d d in their upper edges for receiving rods or shafts e e, to which curved wings O G are fixed, and these, when closed together with the end pieces 0 0, attached to the arms A A, form the receptacle for containing the material. The wings C may have straight surfaces, if preferred.

The rod 0 has attached to it, outside of the scale, a lever, D, having a counter-weight, E, and stop-pin f near the outer end. The inner end is slotted, and carries an adjustable pin, 1', which works loosely in the slotted end of an-. other lever, D, which is attached to the rear shaft 0, carrying the other curved win This lever D is L-shaped, and has at its upper end a pin, 17, or friction-roll. All these parts move move with the scale, and form a part of it.

G is a regulating-lever, which works on a pivot, 4r. Its upper end is brought to a pointi and its lower end has a notch, or, and also cart ries a movable piece, G, covering said notch; This movable piece is held down by a spring 1). This lever Gris held out of the perpendici lar by the pin i on the scale-lever 1), only} however, when the scale is in the act of r ceiving material. As soon as the scale has ret ceived its quota it descends until the pin i anrives opposite the notch m, when the lever being relieved, changes its position instantly thus allowing the upper end to engage wit one of the teeth of a wheel, H, attached to th delivery-apron roll. The wheel H is provide on its periphery with a series of teeth, and ii substitutedfor'a single pin and lever, as show in my former patent, above referred to, an acts on a clutch, substantially the same a therein shown, the only difference being awho with a series of teeth, instead of a short lev with one tooth or pin only. Having incl 1 points of contact, the deliveryof material more promptly cut off through the action of the lever Gr than when only one point of contact presented itself. The scale having received a supply and in oveil downward until the pin i has entered the notch m in the lever G, itis arrested from furthtir movement bythe stop I. The parts all reinai 1 in this position until the time arrives for di charging the scale, which will be longer or shorter, depending on the length of time it nn have taken the scale to receive its supply, whi r latter necessarily varies in proportion to the amount of stock or material deposited withiti the scale in a given time. The discharging is done by a wheel, J, which is attached to the shaft of the feedroll K, anid has two pins, 1) 2, that act on a lever, L, and, through a connecting-rod, s, on a lever, l which has a counter-weight, N, and this kee s all the parts out of contact with the scale, u less acted upon otherwise. hen, howev one of the pins, 1), acts on the lever L, it is( pressed, also depressing the front end of t e lever M, and in its course this comes in conta it with a pin, 8, attached to the lever 1), an d ing with them the wings G 0, thus dropping the material beneath. lVhile this is being done through it also acting on the lever D, carrythe pin 43 has raised the movable piece G of the lever Gr, and, escaping from beneath, allowed the spring 1) to return to its former position, where it now serves as a check on the return of the pin 1' from again entering the notch m in the lever G. By this means the pin 2" presses against the piece G as the wings of the scale are in the act of closing, and thus forces the upper end of the lever G out of contact with the wheel H, which releasesthe clutch above mentioned, and recommences the delivery of a fresh supply to the scale, which has now resmned its original position.

The curved shape of the lever L, as shown, where it is acted upon by the pins 19 p in the wheel J, is such that, by the slow motion of the feed-roll K, the scale is caused to return easily and quietly, without shock or jar.

At 0 is seen a series of changeable weights, by which the amount of material weighed can be changed as desired.

Having thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. A weighing-scale for fibrous or other material, having two curved wings, which, together with suitable end pieces, form a receptacle for containing the substance to be weighed, and which are, at uniform intervals of time, caused to open apart and deposit the material by mechanism, substantially as described, (lisconnected from and independent of the scale, said intervals of time being wholly unaffected, by the time it may take the scale to become balanced, substantially as herein described.

2. In combination with a scale, substantially as described, for weighing fibrous or other material, a pin, 2', or its equivalent, having contact only with and operating the mechanism for arresting the supply of material to thescale, substantially as herein set forth.

i 3. In combination with a scale for weighing fibrous or other material, having a pin,i, or its equivalent, a notched lever or dog, G, for arresting the delivery mechanism, and governed in its action by the balancing of the scale yet unconnected with the latter, or any part thereof, so as not to retard the sensitiveness of the balance, substantially as herein set forth.

4. In combination with a scale for weighing fibrous or other material, having a pin, 1', or its acted upon by means of the rod s, curved lever L, and the pins 19' p on the wheel J, at regular intervals of time, regardless of the time of balancing the scale, and wholly isolated from the weighing mechanism, except at the time of discharge, substantially as herein set forth. In testimony that I claim the foregoing as my own I affiX my signature in presence of two witnesses.
